In a week that starts with low-pressure systems and ends with high-pressure systems, the most accurate forecast would likely be:
dense clouds followed by light wind and clear skies.
This forecast effectively captures the transition from a low-pressure system, which often brings dense clouds and potentially unsettled weather, to a high-pressure system, which typically leads to clearer skies and calmer conditions. The presence of light wind can also be indicative of high-pressure systems.
